Why designers choose it
More current, more pin range, more ways to build
A high-current PCB pin receptacle is a precision-machined socket that mounts on a circuit board or terminates to a wire and accepts a mating pin to carry power. Use one or many wherever your design needs power, or have Mill-Max build them into a complete custom connector with the insulator, spacing and hardware you need.
42 A
Per-contact current rating
Every receptacle is rated 42 A at a 30°C temperature rise, with a 20 percent derated rating of 33.6 A for design planning. The high-force, 6-finger beryllium copper contact minimizes constriction resistance and heat.
.030" (0,76mm)
Mating range, .100" to .130" (2,54mm to 3,30mm)
One receptacle accepts mating pins from .100" to .130" (2,54mm to 3,30mm). Use it when lead size is set by the application, when pins vary across a product line, or when tolerances are wide.
1 or many
Individual receptacles, your layout
Each receptacle is a stand-alone contact, not a position in a fixed housing. Use one or many, in any pattern and at any spacing your layout calls for, on boards, in panels or in cable assemblies.
5 + custom
Termination choice
Open-bottom, closed-bottom and solder-tail versions for the board, plus crimp and solder-cup versions for wire. We can also supply receptacles pre-crimped to wire, and custom shells, materials and plating thicknesses.

Custom connectors
Need a custom power connector? We will build it around these receptacles.
Because every receptacle is a precision-machined part with a press-fit feature, Mill-Max can assemble them into a complete custom connector in house. Tell us what the connector has to do and we will design it with you.
Molded or machined insulators
Injection-molded insulators for production volumes, or insulators machined in house from FR-4 or G-30 polyimide (for extremely high temp applications) with no tooling charge and no minimum order. 3D-printed housings also available to help check form and fit at early design stages.
Your spacing, your pattern
Machined insulators, using in-house milling with tight positional tolerances, lets us match virtually any footprint or contact spacing, so the connector fits your design rather than the other way around.
Power and signal in one connector
Mix and match different receptacle sizes in the same insulator: these high-current receptacles for power alongside smaller receptacles for signal, plus alignment pins where you need them.
Threaded inserts
Add threaded inserts in the same assembly for secure fastening to printed circuit boards, housings or bulk heads.
Pre-crimped wire leads
Receptacles supplied crimped to wire and ready to install, so your team skips the crimping step.
Prototype to production
Prove the design in machined FR-4, then move to a molded insulator when volumes climb. Our engineers recommend the right route for your quantity and timeline.
Features and benefits
Built on our largest 6-finger contact ever
The new beryllium copper contact uses high force and multiple contact points to minimize constriction resistance and heat generation. The result is efficient high-current operation with reliable electrical and mechanical performance under shock and vibration.
Brand-new contact design
Our largest 6-finger contact ever, precision stamped from beryllium copper, heat treated and gold plated, then pressed into a precision-machined shell.
Ultra-low contact resistance
Low-level contact resistance averages 0.5 milliohms. Less heat at the point of contact means efficient energy transfer, stable voltage delivery and less risk of fretting corrosion and micro-arcing.
High contact force
High normal force compresses surface imperfections and breaks through films on the mating pin, minimizing constriction resistance and helping prevent the heat-and-relaxation cycle that leads to thermal runaway.
Reliable under shock and vibration
No electrical discontinuity over 1 µs at 50 g shock or 10 to 2,000 Hz, 20 G vibration, so power stays connected on mobile equipment, in industrial settings and in transportation.
30 µin gold over nickel
Gold plating on the contact provides conductivity, durability and environmental protection.
1,000 mating cycles minimum
Built for docking, service and test applications where connections are made and broken repeatedly.
Inside the receptacle and performance data
The contact is pressed into a precision-machined shell. Force and derating curves show typical values; request samples to evaluate in your application.
Termination flexibility
Five board-to-board and wire-to-board termination styles
Open-bottom, closed-bottom and solder-tail through-hole versions for the board, plus crimp and solder-cup versions for wire. Every style shares the same 42 A, 6-finger contact and the same .100" to .130" (2,54mm to 3,30mm) mating range, so you can mix board-mounted and wire-terminated receptacles in one design.
Series 0386
Closed-Bottom Receptacle
Closed-bottom shell keeps solder and flux out of the contact area during PCB assembly.
Series 0460
Solder-Tail Receptacle
A .080" (2,03mm) diameter solder tail mounts through-hole in the PCB, providing a secure solder joint while preserving critical board space.
Series 0736
Crimp Wire-Termination Receptacle
Crimp barrel for 10 to 12 AWG wire, for fast, repeatable harness and cable assembly.
Series 0765
Solder-Cup Wire-Termination Receptacle
Solder cup accepts wire up to 10 AWG, for hand-soldered power leads and low-volume cable builds.

FAQ
Frequently asked questions
What is a high-current PCB connector?
A high-current PCB connector carries power, not just signal, between a circuit board and another board, component or wire. Mill-Max’s version is a precision-machined pin receptacle with a 6-finger beryllium copper contact, rated 42 A per contact at a 30°C temperature rise.
Who makes these 42 A high-current pin receptacles?
Mill-Max Mfg. Corp. designs and manufactures them in its vertically integrated facility in Oyster Bay, New York. Mill-Max has made precision-machined interconnect components since 1971.
How much current can a pin receptacle carry?
Each of these pin receptacles is rated 42 A at a 30°C temperature rise, with a 20 percent derated rating of 33.6 A for design planning. At the full 42 A rating, operating temperature is specified up to 120°C.
What mating pin sizes do they accept?
They accept mating pins from .100" to .130" (2,54mm to 3,30mm) in diameter, a .030" (0,76mm) range. That suits designs where lead size is set by the application or has wide tolerances.
Board-to-board vs wire-to-board power connectors: which style do I need?
For board-to-board or component-to-board connections, use the PCB-mount styles: open bottom (0361), closed bottom (0386) or solder tail (0460). For wire-to-board or wire-to-wire connections, use crimp for 10 to 12 AWG (0736) or solder cup up to 10 AWG (0765).
How many mating cycles are they rated for?
At least 1,000 mating cycles. They also show no electrical discontinuity over 1 µs at 50 g shock or 10 to 2,000 Hz, 20 G vibration.
What is the contact resistance?
Low-level contact resistance averages 0.5 milliohms, with a 10 milliohm maximum. The high-force 6-finger contact minimizes constriction resistance and heat.
Can these receptacles carry signal as well as power?
They can, but they are designed for power. For connectors that need both, Mill-Max can combine these 42 A receptacles with smaller signal receptacles in one custom insulator.
Can Mill-Max build these into a custom power connector?
Yes. Mill-Max can mold the insulator or machine it from FR-4 or G-30 polyimide with no tooling charge and no minimum order. It can also set custom spacing and patterns, add threaded inserts, and supply receptacles pre-crimped to wire.
How do I get samples?
Use Order Sample in the ordering table. Requests need a free Mill-Max account. Stocked parts can also be bought from DigiKey and Mouser.
